Scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are looking for ways to help specialty crops beat the heat. A new study has identified genes that may help plants cope with stress from high temperatures. It could set the stage for developing crops bred for enhanced heat tolerance, said Bala Rathinasabapathi, senior author of the …
Artificial Intelligence: Helps Detect Watermelon Disease Quickly, Accurately
The needs of Florida watermelon producers motivate Yiannis Ampatzidis to use artificial intelligence (AI) to detect pathogens early and accurately. One such disease, downy mildew, spreads like wildfire, said Ampatzidis, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of agricultural and biological engineering. In newly published research, Ampatzidis used spectral reflectance — the energy a …
Diamondback Moth Management: Insecticide Resistance Concerns Exist
By Clint Thompson Brassica growers rely almost entirely on insecticides to manage diamondback moth (DBM) infestations. However, the moths have shown the ability to develop resistance to a broad range of insecticides, says Hugh Smith, an associate professor of entomology and nematology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Gulf Coast Research and Education Center. …
Resistance Concerns in Insecticide Management of DBM

Water and Soil pH Critical to Citrus Nutrition
There 17 essential elements that plants need to grow. Three of those elements come to plants via water and the atmosphere. The 14 other elements come from fertilizer applications. Almost all of those are dependent on soil pH to determine how well they are picked up by plants’ root systems. Getting the soil pH just right was discussed in the …
Tomato Season: Prepare for Bacterial Spot
By Clint Thompson Tomato season may have just ended in North Florida, but the fall crop will soon be planted. Josh Freeman, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor in horticultural science, estimates planting will begin around July 20-23. But growers should be mindful of one disease that could threaten the fall crop, especially amid …

Complimentary registration is available for all growers, packers, shippers, processors, association members and university researchers. Those interested can click here for additional information. Josh McGill, show director, discusses …
Finding a Fit for Blackberries in Florida
By Frank Giles Blackberries have been produced in Florida for some time, but new efforts have been made to learn more about the crop to grow production and markets in the state. Blackberries have been proven to be a popular item at U-pick operations. For farmers who grow U-pick strawberries and blueberries, blackberries offer a way to extend the picking …
Proposed Changes to Ag Water Requirements
By Taylor O’Bannon, Matt Krug and Michelle Danyluk In December 2021, the Food and Drug Administration (FDA) released its proposed changes to the Food Safety Modernization Act (FSMA) Produce Safety Rule (PSR) Subpart E, which covers agricultural water. Compliance with the requirements of Subpart E has been delayed, since December 2019, to allow FDA adequate time to identify more appropriate …
